Abstract (en)
[origin: US2017102096A1] A balanced port pressure regulator includes a valve body having a fluid inlet and a fluid outlet connected by a fluid passageway, an orifice being disposed between the fluid inlet and the fluid outlet. A valve seat is disposed within the fluid passageway. A valve plug is also disposed within the fluid passageway. A piston is disposed within the valve body, the piston separating the fluid passageway from a balancing chamber. A sleeve extends away from the piston, the sleeve forming a balancing passage that fluidly connects the fluid passageway with the balancing chamber. The sleeve includes an open end that terminates within the orifice. By terminating within the orifice, the open end of the sleeve generates boost only towards the end of a valve opening cycle when the valve plug approaches a fully open position, which is where boost is most needed.
